l I Application iiled December?, 1903. `Serial No. 184,135.

To a/ZZ whom it may concern:

Be it known that 1, EMTLE BoIvIN, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new. and useful Improvements in Radiator-Burners for Spirit-Lamps, of which the following is a` specification.

The spirit-lamp burner vwhich forms the object of the present application is distinguished from other burners ofthe kind by the novel arrangement in the chamber for the mixture of gases of-a heating-radiator, the object and advantage of which vis to insure dry vapors anda suitable form for the flame-that is to say, the form of a candle-llame-whichrenders the ma'ntle incandescent, and when the radiator and the parts dependent thereonare thoroughlyheated the mantle furnishes and maintains its maximum illuminating power, while a great saving of spirit is effected.

The object and advantages of the radiator, which is the essential feature'of the invention, are as follows: e

First. After the lamp hasV been alight for some time this radiator becomes heated through out and transmits this heat by contact to the interior of the tubes c, in which vapori-4 zation is effected. This transmission of heat is intended to dry the vapors thus produced and to-render them suitable for partial and complete combustion.

Second. Independently ofthe form of the llame produced by the radiator as mentioned above the radiator proper, e, in consequence of its special form and the vertical slots formed in it promotes the movement ofv the dry vapors Which come from the'mixing-chamber d.

In order to make the invention quite clear,

it is illustrated in the accompanying drawings. v

Figure 1 is an elevation ofthe burner surmounted by the heating-radiator and the rod for supporting the mantle; Fig. 2, a vertical of the ejector shown in Figs. 1,2, and 6; Fig. 6, a Vertical section ofthe burner, taken at right angles -to Fig. 2; and Fig. 7, a plan of the burner.

Asshown in Figs. 1 and 2, the burner con` sists of a central tube a, which dips into the reservoir or body ofthe lamp. This tube is furnished with asuitable internal wick b. Ata

certain height the tube a is surmounted by two flat tubes c, placed suflicientlyiapart for reber d, Figs. 1, 2, and 4. The mixing-charliber d is brazed to the tube c and tothe bottomof the radiatore, through-which it runs. To the circumference of the basev of the radiator e the heater f islikewise brazed, which is formed by a tube open at the two ends and having two diametrically opposite openings. On the top. of the heater f is a head-piece formed by a ring g, closed at one end by wiregauze L, through which the upper part of the radiator` extends. The two side. tubes c are closed at the top by theirV abutments and by being held in a circular recess formed in the base of the radiator e. ln the interior of each of these tubes is one arm of a U-shaped tube c, the junctional horizontal part of which tube c' is drilled with 'a hole communicating with the holes in a pipe la, with an internal regulating-valve Z, which passes across an ejector m, arranged on and brazed to the top of the tube c. The base of the ejector-m is drilled with two holes a registering with the two flat tubes c and permitting the passage of the spiritvapors from the wick up into said iiat tubes.

The regulatingjvalve Z, by means of whichthe vaporizi'ng operation can be started or the action of the burner be stopped, is-operated from the outsideby a milled nuto, Figs. 1,4 6, and 7. The radiator e is slightly conical and hol# lowed out inside. In the sides thereof are a number of vertical slots p. The top of the radiator, which runs through the gauze-wire 7i, receives the rod q and mantle-holder r. The radiator isplaced over the mixing-chamber and is intended tov difuse the vapors issuing from the ejector m in order to give them a desired form and heat them more and more until a complete diifusion thereof is effected. This heating is effected by conduction-that is to say, through the conductive power of the radiator to the heater and' from the heater tothe tubes o without any external action.

The igniting of the burner may be effected in any manner, but preferably by the device described in relation to Figs. 1 and 7 of the accompanying drawings. This device consists of a cylinder s, drilled near the top with an opening z5, through which the spirit enters from the body of the lamp. To the bottom of this device an elevating-tube u is fitted, the top of which enters the igniting-pan e and is then bent toward the bottom of the vessel. The upper part of the cylinder s carries a tube fw, which acts as a guide for the rod m of a piston y, arranged in the cylinder and the top of which is under the permanent action of a spring 2. The upper part of the piston-rod is bent outside the gallery a in order that it may be lowered when the ignition is effected. An orifice b is formed in the gallery a to allow of the introduction of a match and the igniting of the spirit which has been forced out of the cylinder s into the vessel e by means of the piston y. This arrangement is suitable where simple refined spirit is employed for lighting purposes; but when for any reason whatever carbureted spirit is employed this spirit would not be suitable for the ignition, and therefore I reserve the right of isolating the above-described pump device in a reservoir-tube which is immersed in the body of a lamp and into which spirit is poured suitable for several ignitions.

The burner thus described acts as follows: rIhe lighting or priming is effected as stated. The spirit is drawn up by capillary action near to the ejector m. The vaporization begins in the central tube a and the vapors ascend to the side tube c, which they enter, thence escaping through the ejector and reaching the mixing-tube d become mixed, are diffused and heated by the radiator e, and finally pass through the wire-gauze t, taking the form desired for the mantle.

What I claim, and desire to secure by Letters Patent, isM

1. In an incandescentlamp burner, the combination with a mixing-chamber, of two upright vaporiZing-tubes adjacent thereto, and a U-shaped pipe having a leg in each tube and provided with an aperture in its horizontal part in line with said mixing-chamber.

2. In an incandescent-lamp burner, the combination with a wick-tube, of two fiat Vaporizing-tubes extending up therefrom and closed at their upper ends, a mixing-chamber hetween said vaporizing-tubes, a U-shaped pipe having a leg in each fiat tube and provided with an aperture in line with said mixingchamber, and a radiator above said mixingchamber.

3. The combination with a wick-tube, of an ejector having a base closing the top of said tube and provided with two holes, vaporizingtubes registering with said holes, a heater having open sides and inclosing and supporting said tubes, a mixing-chamber between the vaporiZing-tubes, a U-shaped pipe in said tubes having its horizontal portion extending across said ejector and provided with an aperture communicating with the ejector, a valve controlling said ejector, and a 4slotted radiator surmounting said heater above the mixing-chamber.

In testimony that I claim the foregoing I have hereunto set my hand this 23d day of November, 1903.

EM ILE BOIVIN.
